Gate-controlled photo-oxidation of graphene for electronic structure modification
Ryo Nouchi, Morihiro Matsumoto, Nobuhiko Mitoma
Graphene is an ultrathin material, which allows us to control surface phenomena by means of field-effect gating. Among various surface phenomena, photo-oxidation is known to be a f…
Suppression of excess oxygen for environmentally stable amorphous In-Si-O thin-film transistors
Shinya Aikawa, Nobuhiko Mitoma, Takio Kizu +2
We discuss the environmental instability of amorphous indium oxide (InOx)-based thin-film transistors (TFTs) in terms of the excess oxygen in the semiconductor films. A comparison…
Robustness of Spin Polarization in Graphene-based Spin Valves
Masashi Shiraishi, Megumi Ohishi, Ryo Nouchi +3
Decrease of spin polarization in spintronics devices under an application of bias voltage is one of currently important problems which should be solved. We reveal unprecedented rob…
